29 Scarab, handles the waves great. Not sure if your referring to quartering seas. I just drop the tabs a bit to offset for it. I have a single 502, but I heard the 29 with twins handles even better due to the extra weight.
My boat runs between 75 and 80 with my low psi whipple motor. There may be a couple of board members here that run in the upper 80's. I'm sure they will chime in on this. Mine is set-up for some big HP. I will be selling mine soon. If your interested let me know. I have a deal for some one they can't refuse.
